I am attaching a download link so you can download the instructions that show how to replace the lamp. You can get the replacement lamp from www.tvrepairworld.com and the instructions are at the following link http://www.mediafire.com/?tse1r3ofs2q89lq

The ballast board will need replacement you can get the sony Lamp ballast 146892712 used in the KDF55WF655 models, from www.tvrepairworld.com listed under the sony DLP circuit board cxategory

the optical block will need replacement or rebuild but your still looking at a 500 plus repair

Ur hear alots clicking,but no picture come on?Yes,than the tv Ballast board is also dead.This tv Ballast board,job is to help to ignite the tv projection lamp.Tries websites like Partstore.com,Ebay.com to buy a new tv Ballast board for the replacement.

you can try these steps if this doesn't work I suggest replacing IC8002 on the power supply
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks

If you have replaced Lamp and you still have no picture or Lamp is not Lighting then its the Ballast Board Call Encompass Parts 1-800-638-3328 Make sure your Fans are running this too will cause set not to come on.

call a qualified repair person

Could be a bad lamp again. If this TV uses the XL2200 lamp, they are known for this intermittent behavior. If its not the lamp, a tech can access the self-diagnosis screen to see what's causing this failure.

My kdf55wf655 did this for about a week until I put in a new Lamp. Working fine since then. Got it through Amazon from www.vanns.com.

tv turned off black screen and red light flashes 6 times over and over again
